DENTIN POST: A Challenging Post For Commercially Available Posts.

Ideal coronal reconstruction of endodontically treated tooth is still a challenge for restorative dentistry. Despite having varied types of commercially available posts, none of them meet all the ideal biological and mechanical properties. In this context a ?Biological Post? serves as a homologous recipe for intraradicular rehabilitation of a fractured endodontically treated tooth by virtue of its biomimetic property. This case report addresses the esthetic and functional restoration of a fractured, endodontically treated maxillary left central incisor in a young patient, through the preparation and adhesive cementation of a ?Biological Post? made from a freshly extracted, intact human canine. The use of biological post can be considered as a novel alternative technique for the rehabilitation of an extensively damaged tooth.
